This game has a lot of regional differences, but I'll only cover the Haggar related ones here.

Japanese	European
At the VS. screen, Haggar's signature is just "Haggar" in the Japanese version and "Mike Haggar" in Europe.

Japanese	European
At the winner/loser screen, every losing character has some Kanji next to their portrait, this was removed from the European version. Also, the winner will say something in Japanese, but again this was removed from the Euro version. This is what Haggar says in the Japanese version.

Japanese	European
The Japanese version has bios for every character that would display in attract mode. These were taken out of the European version, and instead replaced with a how to play the game sequence.
